Description of changes:
Adds a unit test to verify that we respect if a customer manually sets their Trace Header for an AWS SDK request, and don't overwrite it with our own header. This is for cases like SFN which are long-running and may require the customer to pass in custom headers which correspond to a particular in-flight execution.
